Scientists, Uncertainty And Nature, An Analysis Of The Development, Implementation And Unintended Consequences Of The Northwest Forest Plan, Gilbert David Miller

Dissertations and Theses

The conflict in the Pacific Northwest between competing visions of how federal forests should be managed resulted in a political stalemate in the early 1990s. The Northwest Forest Plan (NWFP) was initiated to resolve the demands for maintaining ecosystem processes and biological diversity with the social and economic needs for timber harvest. The foundation for the plan rested with the development of ecosystem management. The intent of this research is to explore the events which led up to the adoption of the NWFP, how it was implemented by the US Forest Service and Bureau of Land Management and the subsequent …

Earth System Models (ESMs) are essential tools for understanding and predicting global change, but they cannot explicitly resolve hillslope‐scale terrain structures that fundamentally organize water, energy, and biogeochemical stores and fluxes at subgrid scales. Here we bring together hydrologists, Critical Zone scientists, and ESM developers, to explore how hillslope structures may modulate ESM grid‐level water, energy, and biogeochemical fluxes. In contrast to the one‐dimensional (1‐D), 2‐ to 3‐mdeep, and free‐draining soil hydrology in most ESM land models, we hypothesize that 3‐D, lateral ridge‐to‐valley flow through shallow and deep paths and insolation contrasts between sunny and shady slopes are the top …

The Effects Of Matthew’S Storm Surge On Coastal Loblolly Pine And Wax Myrtle Understory Regeneration, Brynn D. Wilkinson

Journal of the South Carolina Academy of Science

Hurricanes have detrimental effects on the environment and the economy. Not only are these effects felt immediately after the hurricane, but they last long after the winds have died down. They can affect future plant growth and mortality. In October of 2016 South Carolina was hit by Hurricane Matthew, a category 5 hurricane. Hobcaw Barony, our study site, was in the direct path of the storm. This created an opportunity to study the immediate effects on regeneration after a hurricane. Regenerations rates were measured along and around a surge line to determine regeneration and mortality rates. This data also allowed …

Public Land Management On The Upper Mississippi: Exploring Relationships Between Management Imperatives And Ecosystem Biodiversity, Hunter Colleen Ridley

Geography: Student Scholarship & Creative Works

Presently, public land management structure tends to disregard the interconnected nature of the social and ecological systems within managed landscapes. Since these social and ecological systems so heavily influence the identity of landscapes, it is critical that land managers understand the interactions and effects land management has with ecological structure and function. This knowledge helps land managers create more effective, sustainable, and efficient management plans and decisions. This research uses a portion of Upper Mississippi River as a case study for analyzing and discussing public land management on the Mississippi and how its structure may be influencing the ecological identity …

The Influence Of Location On Water Quality Perceptions Across A Geographic And Socioeconomic Gradient In Appalachia, Ross G. Andrew, Robert C. Burns, Mary E. Allen

Faculty & Staff Scholarship

Abstract: Understanding perceptions of water quality held by residents is critical to address gaps in public awareness and knowledge and may provide insight into what defines communities that are more/less resilient to changing water conditions locally. We sought to identify spatial patterns of water quality perceptions gathered in a survey of Southern West Virginia (WV) residents during spring/summer 2018. Using over 500 survey responses across 15 counties, we calculated spatial autocorrelation metrics and modeled the relationships between overall water quality perceptions and county-level socioeconomic endpoints, such as poverty rate, per capita income, and education level. We identified significant differences across …

Temporal Changes In Fruit Production Between Recurrent Prescribed Burns In Pine Woodlands Of The Ouachita Mountains, Tamara B. Wood, Christopher E. Comer, Roger W. Perry, Brian P. Oswald

Faculty Publications

The use of prescribed fire is integral to the restoration of open woodlands and savannas, including shortleaf pine (Pinus echinata) woodlands in the Ouachita Mountains of Oklahoma and Arkansas. Fire offers many potential benefits to numerous wildlife; however, short-term implications for understory fruit production are not fully understood, especially in stands subjected to frequent, recurrent burns. We examined the effects of dormant season prescribed burns on woody fruit production (kg ha−1) and fruit producing vegetative cover in the understory of restored pine woodlands. We inventoried 32 stands during four temporal periods after dormant season prescribed fires: 1, 2, …

Individual Tree And Stand-Level Carbon And Nutrient Contents Across One Rotation Of Loblolly Pine Plantations On A Reclaimed Surface Mine, Hannah Z. Angel, Jeremy S. Priest, Jeremy P. Stovall, Brian P. Oswald, Hans M. Williams

Faculty Publications

While reclaimed loblolly pine (Pinus taeda L.) plantations in east Texas, USA have demonstrated similar aboveground productivity levels relative to unmined forests, there is interest in assessing carbon (C) and nutrients in aboveground components of reclaimed trees. Numerous studies have previously documented aboveground biomass, C, and nutrient contents in loblolly pine plantations; however, similar data have not been collected on mined lands. We investigated C, N, P, K, Ca, and Mg aboveground contents for first-rotation loblolly pine growing on reclaimed mined lands in the Gulf Coastal Plain over a 32-year chronosequence and correlated elemental rates to stand age, stem …

Resin Flow In Loblolly And Shortleaf Pines Used By Red-Cockaded Woodpeckers, David L. Kulhavy, W G. Ross, J H. Sun, Daniel Unger, I-Kuai Hung, Richard N. Conner

Faculty Publications

We measured resin flow in loblolly (Pinus taeda L.) and shortleaf (Pinus echinata Mill.) pines in stands used by red-cockaded woodpecker, Picoides borealis (Vieillot), in the Angelina and Davy Crockett National Forests in eastern Texas. We also measured resin flow in a mature loblolly pine stand not used by the woodpeckers. Resin flow varied by study area, species, and stand position. In woodpecker stands, pines experiencing low levels of competition seemed better able to tolerate the continual resin drainage associated with red-cockaded woodpecker resin well pecking. In the Angelina National Forest, all new cavity trees excavated during the study were …

A New Site Index Model For Intensively Managed Loblolly Pine (Pinus Taeda) Plantations In The West Gulf Coastal Plain, Kynda R. Trim, Dean W. Coble, Yuhi Weng, Jeremy P. Stovall, I-Kuai Hung

Faculty Publications

Site index (SI) estimation for loblolly pine (Pinus taeda L.) plantations is important for the successful management of this important commercial tree species in the West Gulf Coastal Plain of the United States. This study evaluated various SI models for intensively managed loblolly plantations in the West Gulf Coastal Plain using data collected from permanent plots installed in intensively managed loblolly pine plantations across east Texas and western Louisiana. Six commonly used SI models (Cieszewski GADA model, both Chapman-Richards ADA and GADA models, both Schumacher ADA and GADA models, and McDill-Amateis GADA model) were fit to the data and compared. …

The Impact Of Prescribed Fire On Moth Assemblages In The Boston Mountains And Ozark Highlands, In Arkansas, Erin E. Guerra, Cristina M. Blanco, Jorista Garrie

Journal of the Arkansas Academy of Science

In addition to the impacts of prescribed fires on forest vegetation, this ecosystem process also has dramatic impacts on associated insect assemblages. For herbivorous, terrestrial insects, fire predictably results in a cycle of initial insect population reduction followed by recovery and growth, in which these insect populations exceed pre-fire abundances. We sought to examine if fire-induced disturbance cycles make prescribed burned areas more or less suitable specifically for moths (order Lepidoptera), which is a major food source for, among others, multiple bat species. We surveyed moth assemblages at 20 burned and 20 unburned sites in the Boston Mountain and Ozark …

Converting Coast Redwood/Douglas-Fir Forests To Multiaged Management: Residual Stand Damage, Tree Growth, And Regeneration, Robert Thomas Muma

Cal Poly Humboldt theses and projects

There is increased interest in multiaged management as a silvicultural and restoration tool in redwood forests of California. The effect of varying residual densities and spatial arrangements on residual stand damage, tree growth and regeneration was studied in a multicohort silviculture experiment on Jackson Demonstration State Forest. Four treatments varying in residual stand density or spatial arrangement were replicated at four sites. The experiment provided 4-year periodic growth measurements of residual trees and annual measurements of redwood and tanoak sprout height increments. Residual trees were more likely to sustain bole scarring when retained at higher densities. Crown damage was more …

The Impact Of Tree Species, Elevated Nitrogen Deposition, Stand Age, And Environmental Factors On Herbaceous Plant Communities In A Central Appalachian Hardwood Forest, Lacey J. Smith

Graduate Theses, Dissertations, and Problem Reports (ETD)

Although the herb layer represents less than 1% of the biomass of temperate forests, this layer may contain up to 90% of the plant species in the forest and can contribute up to 20% of the foliar litter, thus playing an essential role in forest biodiversity and nutrient cycling. The objectives of this study were to investigate the differences in cover, species richness, Shannon-Wiener diversity, and evenness of herb layer plants a) under tree species associated with contrasting soil nitrogen levels and b) in watersheds that vary in nitrogen deposition, stand age, and watershed aspect at the Fernow Experimental Forest …

Influence Of Climate Change And Prescribed Fire On Habitat Suitability And Abundance Of The High-Elevation Endemic Cow Knob Salamander (Plethodon Punctatus), Carl David Jacobsen

Graduate Theses, Dissertations, and Problem Reports (ETD)

Amphibians are facing global declines due to climate change, loss and degradation of habitat, invasive species, and disease. The Appalachian region of the eastern USA is a global biodiversity hotspot for salamanders, which are considered keystone species that influence nutrient dynamics in terrestrial and aquatic food webs. There are high rates of salamander endemism in the Appalachian region, with many species restricted to isolated, high elevation areas. The Cow Knob Salamander (Plethodon punctatus) is one such species. It is only found at elevations >675 m (most populations are above 900 m) on Shenandoah Mountain, North Mountain, and Nathaniel …

Island Invasion: The Silent Crisis In Hawaii, Sophia Janssen

Pomona Senior Theses

Keeping out invasive species may, upon first review, seem like a trivial environmental cry from ecologists and deep environmentalists; a belated wish to return to an undeveloped world where nature was pristine. However invasive species create problems that impact all of us and can have far more severe consequences than changing a stunning landscape. These problems are heightened in islands like Hawaii, where the fragile ecosystems have developed over centuries of evolution and adaptation. The introduction of a disease-carrying mosquito can put the people of Hawaii at risk to many vector-born illnesses and create an epidemic, taking human life. The …

Spatial And Temporal Patterns Of Invasive Exotic Plant Species In Response To Timber Harvesting In A Mixed Mesophytic Forest Of Eastern Kentucky, Benjamin Christopher Rasp

Theses and Dissertations--Forestry and Natural Resources

Invasive exotic species (IES) responses to silvicultural treatments eight years after timber harvesting were examined and compared to one-year post-harvest IES survey in University of Kentucky’s Robinson Forest. The temporal effects of harvesting were further compared between harvested and non-harvested watersheds. Analyses were performed to identify IES spatial distribution and determine the relationships between IES presence and disturbance effects, biological, and environmental characteristics. IES prevalence was higher in the harvested watersheds and was influenced by canopy cover, shrub cover and disturbance proximity. Ailanthus altissima and Microstegium vimineum presence in the study area has decreased over time. Comparing to the 1-yr …

Multi-Camera Surveillance System For Time And Motion Studies Of Timber Harvesting Operations, Rafael Luiz Santos De Freitas

Theses and Dissertations--Forestry and Natural Resources

Timber harvesting is an important activity in the state of Kentucky; however, there is still a lack of information about the procedure used by the local loggers. The stump to landing transport of logs with skidders is often the most expensive and time-consuming task in timber harvesting operations. This thesis evaluated the feasibility of using a multi-camera system for time and motion studies of timber harvesting operations. It was installed in 5 skidders in 3 different harvesting sites in Kentucky. The time stamped video provided accurate time consumption data for each work phase of the skidders, which was used to …

Northern Hardwood Silviculture: Preferences Among Family Forest Owners In The Western Upper Peninsula Of Michigan, Alexander C. Helman

Dissertations, Master's Theses and Master's Reports

In the northern hardwood forests of the Western Upper Peninsula of Michigan, single-tree selection is the most commonly used silvicultural system. This system provides both a sustained yield of timber and attempts to emulate the windfall disturbance regime that determines the uneven aged structure of northern hardwood forests. However, with concerns about tree species diversity loss and a lack of early successional forests, even-aged regeneration methods are likely to become an increasingly crucial tool in the toolbox for managing northern hardwood forests of the Lake States. The forests of the Western Upper Peninsula are comprised of a mosaic of ownerships, …
